AMD Radeon R9 M380 vs AMD Radeon R9 M375

AMD Radeon R9 M380

The AMD Radeon R9 M380 is a dedicated mid-range graphics card for laptops. It is based on a 28nm GCN core with 12 compute units and a GDDR5 memory controller. Despite the similar name, the Radeon R7 M380 is a much slower as it features only 10 compute units and DDR3 memory.

Features

Features of the R9-M380 include video decoding for MPEG-4 AVC/H.264, VC-1, MPEG-2, and Flash directly by the AMD GPU. Multi-View Codec (MVC) and MPEG-4 part 2 (DivX, xVid) HD videos are compatible as well.

The R9 series also supports automatic graphics switching between the integrated GPU and discrete GPU. Called Enduro, the technology supersedes AMD's Dynamic Switchable Graphics and is similar to Nvidia's Optimus. Furthermore, the M380 can directly support multiple monitors using Eyefinity Technology if Enduro is disabled.

Other features include ZeroCore to reduce the power consumption when the display is turned off and Power Gating to power down areas of the chip that are not used.

The integrated HD audio processor is able to transmit HD Audio (TrueHD or DTS Master Audio) over HDMI and DisplayPort (e.g., for Blu-Ray videos). Additionally, it allows audio output simultaneously and in parallel to multiple devices with the new Discrete Digital Multipoint Audio (DDMA) feature.

AMD Radeon R9 M375

The AMD Radeon R9 M375 is a dedicated higher mid-range graphics card for laptops. It is still unclear if the M375 is based on a new chip (Tonga derivative with full DirectX 12 and Vulkan support) or the old Cape Verde chip from 2012. The core is clocked at relatively high 1015 MHz, however, the bottleneck may be the use of slow DDR3 graphics memory (128-bit).

The 640 shaders can be used with OpenCL 1.2 for general-purpose calculations (as 10 compute units).
